Answer : An ionic bond is formed when one atom transfers an electron to another atom.
Ionic bond is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal).
Ionic bonds form when one atom gives up one or more electrons to another atom. It is the complete transfer of valence electron(s) between oppositely charged atoms
For example NaCl (sodium chloride ) is an ionic bond, in which valence electron from Na gets completely transferred to the valence shell of Cl and ionic bond is formed between opposite ions that is Na (positive) and Cl (negative).
Note : Ionic bond is formed between metal (electropositive element) and non-metal(electronegative element).
When atoms are subjected to radioactive isotopes, their number of protons or neutrons are changed. This results, not in the formation of ionic bonds, but in their transformation to another element.
When both have high electron affinity, the resulting compound will be molecular or covalent. Covalent compounds are formed by the sharing of electrons of two or more non-metal atoms. When all atoms have high electron affinities, they are more stable upon receiving additional electrons. And since the natural tendency is to get to a more stable state, these atoms will resist transferring their valence electrons since that will make them more unstable. Hence, instead of complete transfer, they would share their valence electrons.
Ionic bonds are the forces of attraction that hold positively charged and negatively charged ions together. Nonpolar molecules result from atoms that equally share their electrons.
If both atoms are electrically neutral, then they are not charged particles. Recall that the ionic bonding results from the attraction between two charged species.
